1 Claim. 1

My invention relates to a wrist band primarily for watches, identification bracelets or the like.

Among the objects of my invention is to provide a wrist band adjustable to receive and hold watches or other objects of different sizes and to be used on wrists of different sizes. My device also has a locking means preventing loss or becoming loosened. My device is simple, improved and economical in construction, lasting in wear and comfortable in use.

My invention also contemplates such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown herein a preferred embodiment of my invention, yet I wish it understood that it is susceptible of modification and change without departing from the spirit of my invention.

Referring to the drawing, Fig. 1 is a front elevational view, Fig. 2 is a top plan view and Fig. 3 is a rear elevational view of my device; Fig. 4 is an enlarged detailed view on line 44 of Fig. 3 partly in section; Fig. 5 is an enlarged detailed sectional view; Fig. 6 is a face view of the removable strap and Fig. 7 is a perspective view of my assembled device.

The embodiment selected to illustrate my invention comprises an elongated box-like member 55 of rectangular cross section and having an interior face 51 and an open end 52. Attached to said interior face 51, adjacent said open end 52, is the rear end 53 of spring 54. Said spring 54 extends diagonally forwardly and upwardly from said open end 52 to transverse embossment 55, beyond which it extends diagonally forwardly and upwardly to free forward end 56.

A rod 51 is positioned in embossment 55 with its ends 58 extending beyond box like member 50.

A removable end member 59 having a plurality of spaced ridges 60 may be forwardly inserted into box like member through open end 52. The forward end 56 of sprin 54 contacts removable end member 59 but does not prevent its forward movement in box like member 50. Rearward movement of member 59 is prevented when end 56 of spring 54 bears against one of the spaced ridges 65.

By manual forward movement on ends 58, rod 51 moves end 56 of spring 54 away from contact with ridges of a removable end member 59 and permits its rearward movement. When manual pressure is released on rod 51, spring 54 returns to contact member 59.

A fixed end member 5| is attached to the other end of said box like member 50.

The outer portions of end members 59 and GI are adapted to receive means for the attachment of a watch, bracelet, or other object. The box like member is adapted to receive engraving for identification purposes.

Having thus described my invention, I claim:

A buckle comprising an elongated box like member of rectangular cross section and having an interior face and an open end, a spring attached at its rear end to the interior face of said box like member adjacent the open end of said box like member and extending diagonally forwardly and upwardly therefrom, said spring having a diagonally forwardly and upwardly extending free front end, said spring having a transverse embossment intermediate its ends, a rod positioned in said embossment and extending beyond said box like member, the free front end of said spring normally contacting a removable member inserted into said box like member through said open end thereof, said rod upon manual forward movement against said spring adapted to move the front end away from contact with the removable member.

ARCHIBALD MACLACHLAN.
